Question

Questions are either Multiple Choice, A. True or B. False, fill in the blank, for short answer. Please choose the single best answer. Fill in the scantron form for all 50 questions. 1. Photosynthesis is one of the most significant metabolic processes on Earth because almost all our energy is ultimately derived from: A. breakdown of inorganic chemicals. B. glycolysis and the TCA cycle. C. solar energy. 2. What term describes organisms that obtain their energy, carbon and electrons through oxidation of organic compounds made by autotrophic organisms? A. chemoorganoheterotrophs; B. photolithoautotroph: C. chemolithoautotrophs 3. A.) True or B.)False In acrobic respiration, when oxygen accepts electrons, water is produced as a byproduct. 4. Pathways with enzymes that function both catabolically and anabolically are often called amphibolic pathways. These pathways have an advantage in that they: A. save energy and materials by using many of the same enzymes for both types of reactions. B. save energy by employing electron transport chains to enhance their effectiveness. C. import enzymes from outside the cell to enhance their productivity and effectiveness. 5. The majority of the ATP produced during aerobic respiration, is produced during which part? A. the electron transport chain; B. glycolysis; C. the activity of the tricarboxylic acid cycle. an organic energy source, the electrons released are 6. When chemoorganotrophs oxidize accepted by electron carriers such as NAD+ and FAD. When these reduced electron carriers (e.g., NADH, FADH2) in turn donate the electrons to an electron transport chain, the metabolic process is called A. respiration; B. glycolysis; C. bioremediation; D. fermentation is an aerobic chemolithotrophic process that ultimately oxidizes ammonia to 7. nitrate, whereas organic compound using an oxidized nitrogenous compound, such as nitrate, as the terminal is a form of anaerobic respiration involving the oxidation of an electron acceptor A. Ammonification; nitrification; B. Denitrification; nitrification; C. Ammonification denitrification; D. Nitrification; denitrification 8. Which of the following can be used as terminal electron acceptors during anaerobic respiration? A. nitrate; B. sulfate; C. carbon dioxide; D. all of the choices gas; B. Reduced nitrogen compounds; C. Reduced sulfur compounds; D. All of the choices are correct. 9. Which of the following may be used as sources of energy by chemolithotrophs? A. Hydrogen 10. A.) True or B.)False All forms of phototropy "harvest" light energy to fix carbon, producing sugar
